There are few things as frightening as watching your dog have a seizure. Yet dog seizure disorders are surprisingly common. A seizure is defined as uncontrolled electrical activity in the brain. Seizures can run the gamut from very minor, focal seizures (a twitching of the face or a leg) to major convulsions in which a dog loses consciousness, may vocalize loudly, has uncontrolled muscle movements, and loses bowel and/or bladder control.
